Module 8.1 Attention and Categorization Cognition: thinking and using knowledge Attention is your tendency to respond and to remember some stimuli more than others at a given time Bottom up process: when something suddenly grabs your attention. Peripheral stimuli control it Ex. A loud noise Preattentive process : stands out immediately. Ex. Swan amongst geese Attentive process: one that requires searching through the items in series Ex. Where's Waldo Top down process : deliberately decide to shift your attention Cannot do two separate things at once Stroop effect: the tendency to read words instead of saying the color of ink When speaking you are primed to read the words you see but when you are pointing you are more primed to attend to nonverbal cues such as ink color Change blindness: the failure to detect changes in parts of a scene Especially unlikely to notice changes if your working memory is occupied with other matters such as the plot of a movie
